Digraphs. A directed graph (or digraph ) is a set of vertices and a collection of directed edges that each connects an ordered pair of vertices. We say that a directed edge points from the first vertex in the pair and points to the second vertex in the pair. We use the names 0 through V-1 for the vertices in a V-vertex graph.Graph theory is the study of mathematical objects known as graphs, which consist of vertices (or nodes) connected by edges. (In the figure below, the vertices are the numbered circles, and the edges join the vertices.) Any scenario in which one wishes to examine the structure of a network of connected objects is potentially a problem for graph theory. …Examples of Complete graph: There are various examples of complete graphs. Some of them are described as follows: Example 1: In the following graph, we have to determine the chromatic number. Solution: There are 4 different colors for 4 different vertices, and none of the colors are the same in the above graph.I might be having a brain fart here but from these two definitions, I actually can't tell the difference between a complete graph and a simple graph.

We start at the source node and keep searching until we find the target node. The frontier contains nodes that we've seen but haven't explored yet. Each iteration, we take a node off the frontier, and add its neighbors to the frontier.Prerequisite – Graph Theory Basics. Given an undirected graph, a matching is a set of edges, such that no two edges share the same vertex. In other words, matching of a graph is a subgraph where each …IMF Director Christine LaGarde gave a speech in Washington Sept. 24 with one main point: Policy matters.
